FAQ
Will a portable monitor work with one cable?
Only if your laptop's USB-C port supports video (DisplayPort Alt Mode or Thunderbolt). If it does, one cable carries both video and power. If not, use HDMI plus a separate power cable.
Can I use a portable monitor with my phone?
Many Android phones and recent iPhones with USB-C video output work. Check that your phone supports wired display output.
Is 1080p enough on a 15.6-inch screen?
Yes, for documents, email and video calls. A 2.5K screen like the ARZOPA is noticeably sharper for detailed work and fits more on screen.
Can I take a portable monitor on a plane?
Yes, it is just a screen without a battery in these models, so it can go in your carry-on. Use the cover or a sleeve to protect the glass.
